A metal sealed organic light emitting diode device comprising a lid, containing a recessed portion to accommodate large quantity of getter/dessicant, a band of metal stack at the perimeter over which is laid a band of low temperature melting solder alloy, pre-tinned subsequently, and a substrate. The substrate containing organic light emitting diode at the central area with a band of metal stack at the perimeter. The lid and the substrate are placed together in substantial alignment such that the pre-tinned low melting solder band of the lid contacts the metal stack of the substrate and thermally sealed in a controlled atmosphere. Multiples of substrates are sealed with a single lid containing multiplicity of recessed portions with multi-segmented metal stack and pre-tinned solder band to derive a large area device.
